18. In 1986, a gargantuan iceberg broke away from the RossIce Shelf in Antarctica. It was approximately a rectangle160 km long, 40.0 km wide, and 250 m thick.(a) What is the mass of this iceberg, given that thedensity of ice is 917 kg/m??(b) How much heat transfer (in joules) is needed to meltit?(c) How many years would it take sunlight alone to meltice this thick, if the ice absorbs an average of100 W/m?, 12.00 h per day?

Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 138 km long, 28.1 km wide, and 247 m thick. (a) How much heat in joules would be required to melt this iceberg (assumed to be at 0 °C) into liquid water at 0 °C? The density of ice is 917 kg/m³. (b) The annual energy consumption by the United States in 1994 was 9.3 x 10¹⁹ J. If this energy were delivered to the iceberg every year, how many years would it take before the ice melted? (a) Number (b) Number Units Units
When you turn your hot water on in the shower, it takes a bit for the water to get warm. Some of this is because the water in the pipe is cold but some of it is because the water from the hot water heater must heat the copper plumbing pipe itself. Copper has a specific heat of 0.39R. How much energy does it take to heat 2 kilograms of copper pipe from 70°F to 130°F? Report your answer in Joules. (Hint: Note that you'll need to convert kJ to J and F to K.)
A hot steel plate with a surface area of 2.17 m2 and a constant surface temperature of 165°C is exposed to ambient air at 24°C. If the convection heat transfer coefficient is 15.4 W/m2· K, what is the rate of heat transfer (in W) from the plate to the air [round your final answer to zero decimal places]?
Suppose you walk into a sauna that has an ambient temperature of 50.0C. (a) Calculate the rate of heat transfer to you by radiation given your skin temperature is 37.0C, the emissivity of skin is 0.98, and the surface area of your body is 1.50 m2. (b) If all other forms of heat transfer are balanced (the net heat transfer is zero), at what rate will your body temperature increase if your mass is 75.0 kg?
Note: Round off your answer up to 3 decimal places. Input only the numerical value. Researchers are conducting a study to quantity the thermal conductivity of a composite material. A square box is made from 838 cm2 sheets of the composite insulating material that is 2.8 cm thick. A 201 W heater is placed inside the box. Sensors attached to the box show that the interior and exterior surfaces of one face have reached the constant temperatures of 81°C and 38°C. What is the thermal conductivity in W/m-K?
